The other major problem with replacing books is that there isn’t an online store that you want to browse the way you will a book store. Jeff Bezos can hump his Kindle until it’s as sticky as a stripper’s shoes, but you don’t browse Amazon, not really. You might link-hop a bit, but face it, Amazon’s strength is that it lets you get shit done like a SEAL sniper. You find your target, take the shot, and get out. That’s not bad, not on any level. It’s one reason why I use, no why I love Amazon so much for buying gifts and the like. They have a lot of stuff, it’s easy to find, and it’s usually pretty cheap. It’s also really easy to get through the whole “trading money for stuff” part of the transaction.
